Prognostic implication of right ventricular-pulmonary artery coupling in valvular heart disease.
Front Cardiovasc Med

Valvular heart disease (VHD) leading to inadequate hemodynamic circulation is a major cause of cardiovascular morbidity and mortality worldwide. Right ventricular-pulmonary artery (RV-PA) coupling integrates the ability of RV contractility to adapt to increased pulmonary arterial afterload. If the right ventricle cannot adapt to the elevated afterload by increasing its contractile function, RV-PA uncoupling occurs.

Introduction: Decreased left atrial appendage emptying velocity (LAAV) is a marker for thrombus formation. This study evaluates the association between LAAV and inflammatory indices in non-valvular atrial fibrillation (AF) patients.
Methods: The study population was 1428 patients with AF, 875 of whom enrolled.
Modeling Heart Failure With Preserved Ejection Fraction Using Human Induced Pluripotent Stem Cell-Derived Cardiac Organoids.
Circ Heart Fail
January 2025
Bruce Rapport Faculty of Medicine, Technion-Israel Institute of Technology, Haifa, Israel (I.R.H., N.K., C.B., O.C.).
Background: The therapeutic armamentarium for heart failure with preserved ejection fraction (HFpEF) remains notably constrained. A factor contributing to this problem could be the scarcity of in vitro models for HFpEF, which hinders progress in developing new therapeutic strategies. Here, we aimed at developing a novel, comorbidity-inspired, human, in vitro model for HFpEF.

Cureus
December 2024
Department of Anaesthesia and Intensive Care, Latifa Hospital, Dubai Health, Dubai, ARE.
We describe, to our knowledge, the first use in Dubai of extracorporeal life support (ECLS) in a patient who suffered intraoperative cardiac arrest due to presumed cardiac channelopathy. A 40-year-old patient presented for open myomectomy surgery. She had no other medical problems apart from obesity.
View Article and Find Full Text PDFIntroduction: The infarcted heart is energetically compromised exhibiting a deficient production of adenosine triphosphate (ATP) and the ensuing impaired contractile function. Short-term blockade of the protein S100A9 improves cardiac performance in mice after myocardial infarction (MI). The implications upon ATP production during this process are not known.
